Your hosting provider must support running code under .NET Full Trust. Medium Trust (the standard shared hosting configuration for ASP.NET) support will be provided with Umbraco 4.1 (currently in beta). [This information is out of date as of January 2015]

While the installation process, a 'invalid object name umbracoUser' error occures[edit]

This error may appear, if the web.config-key "umbracoEnableStat" is changed from false to true prior the installation. The key must not be changed to anything else than false until the installation procedure using the wizard is completed.

It seems it is possible that the installation is ready to continue but for some reason does not do so. Try browsing to http://localhost/install and setup might continue (if your installation is in http://localhost)

This error may also appear when umbraco is installed in a virtual directory. When your virtual directory is named myvirtualdir, change the web.config in a way that the keys umbracoReservedPaths and umbracoPath contain the name of the virtual directory, like <add key="umbracoReservedPaths" value="/myvirtualdir/umbraco,/myvirtualdir/install/" /> and <add key="umbracoPath" value="/myvirtualdir/umbraco" />

The above is perhaps misleading, Umbraco does not support being installed in a virtual directory.

The notification Email message is set in the appropriate localised xml file for he language that you are using in the directory umbraco\config\lang under your Umbraco installation directory.
